WILLIAM H. ELLIOT, OF 'NEW YORK, N. Y.

MAGAZINE FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 250,652, dated December13, 1881.

Application filed September 15,1881. (No model.)

To alltvhom it may concern:

Be it known t-hat I, W'M. Il. ELLIOT, of the city and State of New York,have invented a new and Improved Magazine Fire-Arm, of which thefollowing is a specification.

The object of my invention is to provide a more convenient, simpler, andmore practical magazine fire-arm than any now in use; and the nature ofmy invention consists in the use of certain appliances and methods,which are fully set forth inthefollowingspecification and claims.

Figure l is a vertical longitudinal section of the arm, showing the boltand carrier in elevation. Fig. 2 is a vertical section of the bolt `andan elevation of the carrier and cartridgestop, showing the parts intheir relative positions at the moment the cartridge is carried into thereceiving-chamber. Fig. 3 is a vertical cross-section of the sameatbroken line x, Fig. 1. Fig. 4 is the same at broken line m, Fig. 1.Fig. 5 is an elevation of the forward end of the bolt andcartridge-stop. Fig. 6 is a plan of a portion of the receiver. Fig. 7 isa longitudinal section of a portion of the guardlever. Fig. S is avertical section of aportion of the arm, showing the link-connectionbetween the operating-lever and receiver.

The invention herein described refers to that kind of magazine-arminwhich thebreech-block has a reciprocal movement in a line with thebarrel for opening and closing the chamber, and in which said movementis given to the breech-block by means of a toggle-connection, which hasits upper or leverlink extended rearward under the wrist ofthe arm toform a lever, and is an improvement upon the arm patented to me April26, 1881.

The arm in its closed position is shown in Fig. 1, in which the devicesare represented in the act of firing the charge; and in Fig. 2 the vbolt, carrier, and cartridgestop are shown in their relative positionswhen the arm is open.

For a magazine I employ a single tube provided with the usualcartridge-propelling devices, and located under the barrel.

The receiver of the arm has the barrel a screwed into its forward end,and is also provided with the bar or recoil-shoulder m', cut in thesolid material of the receiver, which connects the two sides of thereceiver together, as shown in Fig. 4.

The operating-lever of the arm is pivoted at its forward end to thedependent portion of the breech-block at c. The forward or short arm ofthe lever forms one link of the toggle-connection, and when the arm isclosed it fits in between the dependent portion of the breechblock at nand the recol-shoulderm, whereby it resists the recoil of the charge.The lever also extends to the rear of the recoil-shoulder m', and hasupon the part so extended rearward the trigger-guard, as shown inFig. 1. The lower or connecting link of the toggle-connection is pivotedat its rear end to the lever or upper link at g", and at its forward endto a fixed point upon the receiver, near the mouth of the magazine. Thetwo joints of the lower link are loose, so as to allow a slightlongitudinal movement in each, to provide for the varying distance Whilethe arm is being closedfhetween the shoulder m" and the point upon thereceiver, to which the lower link is pivoted.

The carrier is pivoted to the receiver, at d', upon the same pivot withthe hammer, as shown in Fig.1. It has an arm, e', which extends upwardinto the groove to in the under side of the breech-block. It has also awidened portion, c,at its forward end,for keeping the cartridge in acentral position. This widened portion is acted upon by the bevel r toforce the carrier slowly down below the mouth of the magazine as thebreech-block moves forward in closing the arm. Ihe last portion of thisforward movement releases the first cartridge in the magazine from thefeed-pawl, which passes upon the carrier when the breechblock makes itsbackward movement. As the breech-block is moved backward in opening thearm the carrier, by the action of spring e', is raised, carrying thecartridge with it up to the receivin g-chamber before the breech-block.If, from any cause, the action of the spring should not bring up thecartridge in time, the movement of the carrier is made positive by theshoulder at the forward end of the groove fw coming in contact with thearm e as the breech-block is completing its backward movement.

The cartridge-stop o', as seen in Fig. 2, is

VIOO

5 5 .which serves to stop the cartridge,

attached to and moves back and forth with the bolt, and also has aparallel movement in the bolt. It is provided at its forward end withtwo points, o and 0".l The former ejects the empty shell. The latterarrests the backward movement of the cartridge as it follows the boltback on leaving the magazine. It is also provided at its rear end withthe point w, which arrests the backward movement of the stop at theproper place. The point w rests upon a portion of the carrier which iscut in the form of a segment, having' its center in the pivot of thecarrier, so that, although the carrier is in motion when it arrests thestop, it

imparts no movement to that device. When acartridge is released from themagazine by the feed-pawl it first comes in contact with the point 0ofthe stop while the arm is yetclosed. The position of the point 0 nowbeing considerably to the rear of the forward end of the bolt, as seenin Fig. 1, the head of the cartridge is lodged under the bolt, where itremains until, by the backward movement of the bolt, the stop is broughtagainst the carrier at w, which arrests the backward movement of thestop and lower side of the head of theshell which is being extracted;but the backward movement of the bolt and extractor being continuedreleases the head of the advancing cartridge from its position under thebolt, so that it can be raised by the carrier, and at the same time theextractor carries the upper side of the head of the empty shell back,which ejects it lfrom the receiver.

In the forward end of the receiver, between that portion of it whichcontains the breech mechanism and the chamber of the barrel, there is asolid partition, t', provided with a circular opening, which allows theforward end of the bolt to pass through it when the arm is closed. Infront of this partition there is an annular recess, i', surrounding theforward end of the bolt and head of the cartridge, which is providedwith gas-escapes t. (Shown in Fig. l and in Fig. 3 by broken lines.) Forthe purpose of making a cheap and perfect fit of the forward end of thebolt in the partition, I make it cylindrical and the holel through thepartition round, except a small recess on the upper sidefor theextractor, and Idivide the forward end of stop o into two parts, thatwhich serves as an ejector coming out of the forward part of theboltwithin the circumference of its cylindrical end, and the other,projecting below the cylindrical end. By this construction ofthe partsan escape of a large quantity of gas from a defective cartridge iscontrolled,

as it must first pass into the annular recess i', and then through theescape i to the open air. An y escape through the extractor-recess wouldalso be to the open air, and none would pass into the receiver. Bydividing the forward end of the stop into two points', as above stated,the cylindrical surface of the forward end of the bolt, and the surfaceof the opening through the solid partition are left unbroken, whichmakes theescape of gas into the receiver im-4 possible, as the openingin the end ot' the bolt for the ejector-point is completely covered bythe head of the cartridge, while at the same time both the cartridgestop and ejector are constructed in one piece of mechanism, thearrangement ofthe two points being such that while the lower pointpushes the advancing cartridge out from under the end of the bolt theupper point ejects the empty shell from the receiver.

By reference to Fig. 6 it maybe seen that the opening to thereceiving-chamber a on the top of the receiver is narrowed for a shortdistance at its rear end by the projections r'. The location of theopening a' in relation to the rest of the breech mechanism is such thatwhen the cartridge is raised by the carrier its head comes np under thenarrow portion of the opening, as seen at b, which is too narrow toallow the head to be thrown out of the receiving-chamber by the carrier,while the upl ward movement of the forward end of the cartridge isarrested by an overhanging portion of the receiver. After the cartridgehas been fired the shell is drawn back by the extractor to the positionrepresented by broken lines b",

`from whence it is ejected from the receiver in the manner alreadydescribed. As the backward movement of the lower edge of thecartridgehead is arrested by the ejector the extractor gives to theforward end of the cartridge-shell an upward-and'backward movement in avertical plane, which imparts to the head ofthe shell a forwardmovement, causing it to swin g forward from under the narrow part of theopening into the wide p'art, from whence it readily escapes from thereceiver, turning upon a horizontal axis located about half an inch fromthe head of the shell.

By reference to Figs. 1, 4, and 7 it may be seen that the lever ghasupon its forward end a segmental projection, a', having its center inthe axis of the pivot c, which, when the arm is manipulated, moves alongupon the ledges a within the receiver, and that the bolt is providedwith parallel projections a" upon its upper side, which extend from apoint within half an inch of -its forward end to its rear end, and theseprojections serve as a cover to the receiving-chamber, the top of thereceiver being cut as shown in Fig. 4, so as to furnish a surface forthe projections a" to slide upon. As the lever moves back and forth inmanipulating the arm the segmental projections have a partial .rotationaround the pivot c", having .at all times a bearing upon the ledges a,to prevent any upward movement of the forward end of the bolt. 'Theobject of this construction of parts is to provide guides for theforward end of the bolt, to prevent unusual friction while the arm isbeing manipulated.

l The ejector o may be made independent of the stop o' and operated by aspring, as shown in my patent before mentioned. By this con- IOO IIO

IZO

struction a cartridge-shell would be ejected a little earlier in thebackward movement of the bolt. In that case the device o would act as acartridge-stop only.

By reference to Figs. 1 and 7 it may be seen that both links of thetoggle-connection are recessed to make room for the carrier, whichoccupies a central position.

Having described my invention, what I desire to have secured to me byLetters Patent of the United States is 1. In a magazine fire-arm havinga breechblock for closing the chamber, which moves in a line with thebarrel, a centrally-aman ged carrier for raising the cartridge, providedwith the segmental bearing for the point w, and inV combinationtherewith a centrallyarranged cartridge-stop, which is attached to andmoved with the bolt, and has its rearward movement arrested by thecarrier, substantially as specified.

2. In a magazine re-arm having a breechblock for closing the chamber,which moves in a line with the barrel, a carrier for raisingthecartridge, which is provided with the segmental surfacefor the point w",and in combination therewith a cartridge-stop which is provided at itsforward end with two points, one projecting from within the cylindricalend of the bolt to eject the empty shell, the other acting below thebolt to arrest the backward movement of the cartridge and push it ontfrom under the bolt, said stop having its rearward movement arrested bythe carrier, substantially as specified.

3. In a breech-loading fire-arm having a breech-block for closing thechamber, which moves in a line with the barrel, and a receiver providedwith the ledges a, and in combination therewith a bolt provided with'thecover or projections nmto slide upon Vthe top ofthe receiver, and alever which is pivoted to said bolt, and is provided with the segmentalprojections a to run upon the ledges a, substantially as and for thepurpose specified.
